Abstract

This paper discusses the analysis of the effect of the permeance function harmonics induced by dynamic air-gap eccentricity in squirrel cage induction machines and explains the mechanism of generation of the harmonic components in the stator current spectrum. An analytical expressions of the motor inductance have been derived using the decomposition into Fourier series of both winding function approach (WFA) and the permeance function. Experimental results have been presented to validate the analytical and simulation results.
